My system specs are
8800gtx sli oc
core2duo 3.1ghz
2gb ddr2
windows xp
1920x1200

 

My system runs fine usualy with everything highest quality except antialiasing. When ever I crank up antialiasing even only 2x my fps drops to ~46-60. I mostly play online shooters so I want to stay above 60 all the time if possible. Any thoughts as to why I cant get constant fps with just 2x AA. I play mostly HL2 source games and mods.

 

I already tried lowering AF etc.. and other things, but those dont seem to be affecting my performance as much as AA. It seems as though no matter what middle ground I try to find in the quality settings, i can never use AA. I would be happy with just 2x AA to tame those jaggies a little.

 

Any tips on how to get there? Is this a driver bug, software problem, or my hardware? Maybe something inside my nvidia control pannel holding me back that I dunno about? I know SLi is enabled in there.

Force 4x AA in the control panel (4x much better then 2x, MUCH).

4x and your res should give you 99% perfect picture.

Are you using the latest Nvidia drivers? I found in certain games they made SLI a lot mroe effective for me.
